MANTLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 758,814, dated May 3, 1904.

Application filed December 24, 1902. Renewed February 23, 1904:. Serial No. 194,881. (No model.)

To all whom it 711/601] concern:

Be it known that I, WILLIAM E. BLAIR, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York. have invented certain new and useful Improvements in Mantle Supports, of which the following is a specification.

My invention relates to a mantle-support such as used in incandescent gas-burners; and the object of my invention is to construct a support of this character which will effectually take up all vertical vibrations, and thus lengthen the life of the mantles, which easily become broken owing to their fragile nature.

Other objects are to provide a support with yielding means through which cold air can circulate, and thereby keep the parts cool, to provide a simple, durable, and economical support which will at all times be held in a vertical position without being affected by the heat, and to provide a tube on which the wire support is held in a vertical position.

The invention consists of the new and novel arrangement and combination of parts as will be hereinafter described, and more particularly pointed out in the subjoined claims.

In the drawings, Figure 1 is a sectional elevation of a gas-burner, showing my improved mantle-support forming part thereof. Fig. 2 is an enlarged central vertical section through the support, showing a portion of the burner proper. Fig. 3 is a cross-section of the same on a still further enlarged scale.

Referring to the drawings in detail, like numerals of reference refer to like parts in the several figures.

The numeral 1 designates the gas-fixture, 2 the burner-chamber, 3 the chimney-gallery, and a the air-mixer, all being common to burners of this type.-

5 designates the mantle, which is supported on my improved support 6.

The mantle-support consists of a cylindrical tube 7, open at both ends and having its lower end reduced in diameter, as at 8, to fit the usual socket 9, with which most all incandescent burners are provided and in which it is rigidly secured. The said tube is provided with small perforations 10 throughout its length and has its meeting ends directed inthe mantle is attached.

wardly at an angle, as at 11, to form a longitudinal groove 12.

13 designates the yielding wire support, having the usual lateral extension 11 at its upper end terminating in a hook 15, to which This, however, may be changed to suit ones desire and forms no part of my invention. The said wire support is provided with a spiral spring 16 at its lower end, which surrounds the rigid tube and bears against the socket portion of the burner. This spring is gradually enlarged from both ends toward the center to provide an air-passage 17 between the tube 7 and the intermediate convolutions of the spring, thus keeping the said spring cool at all times to retain the temper of the same. In addition to providing this air-passage the spring is positioned considerably below the mantle and out of the heat zone. The yielding support 13 is provided with one or more loops 18, which encircle the tube 7 and hold said support against the latter. It is also provided with one or more offset-s 19, which enter the groove 12 and prevent the turning of the support on the tube, thereby causing the hook 15 to be held directly over the center of the burner-chamber at all times and preventing the mantle from accidentally swaying to one side, which would destroy the same.

In ordinary burners the mantle-support becomes intensely heated and bends upon itself. This crowds the mantle down and forces the same out of line with the burner, thereby effecting the lighting efficiency of the same or causing complete destruction. This is obviated entirely by my invention, since the tube 7 supports the wire support throughout its length and prevents the same from bending upon itself. The tube 7 as designed permits the cold air to enter the loweropen end of the same and also to enter through the perforations therein, which circulates therethrough and keeps the tube cool and also the yielding wire support held thereon.

I wish it to be particularly understood that I do not wish to confine myself to the precise details herein set forth and shown in the accompanying drawings, as the invention is susceptible to various changes in form, proportion, and in the details of construction without departing from the principle or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim is 1. A mantle-support comprising a rigid member supported on the burner, and a yielding member guided in its movements on said rigid member and being adapted to take up vertical vibrations.

2. In an incandescent gas-burner, the combination of a yielding mantle-support having a spring at its lower end to take up vertical vibrations, and means for guiding said support in its movements.

3. In an incandescent gas-burner having a mantle, the combination of a rigid member supported in the burner, and a yielding member movable lengthwise on said rigid member.

4. A mantle-support comprising atube, and a wire support afiixed to said tube to prevent said support from bending upon itself when highly heated.

5. In an incandescent gas-burner having a mantle, the combination of a tube rigidly supported in the burner, and a yielding support guided on said tube and bearing with its lower end against a portion of the burner, said support having the mantle attached thereto.

6. In an incandescent gas-burner having a mantle, the combination of a tube open at both ends and being rigidly supported in the burner, and a wire support guided on said tube and having a spring at its lower end which bears against the burner, said support having the mantle attached thereto.

7 In an incandescent gas-burner having a mantle, the combination of a tube rigidly supported in the burner, and a yielding support guided by said tube and having loops surrounding the same, said support having the mantle attached thereto.

8. In an incandescent gas-burner having a mantle, the combination of a tube rigidly supported in the burner, a wire support guided on said tube and having a spiral spring surrounding the lower end of the same, said spring bearing against the burner and said support having the mantle attached thereto.

9. In an incandescent gas-burner having a mantle, the combination of a tube rigidly secured in the burner, and a wire support for the mantle guided on said tube and having a spiral spring surrounding the lower end of the same, said spring having its convolution gradually enlarged from both ends toward the center to form an air-passage between the same and the said tube.

10. In an incandescent gas-burner having a mantle, the combination of a tube rigidly supported in a vertical position on the burner, a wire support having loops surrounding said tube and a spiral spring at its lower end also surrounding said tube, said support having the mantle attached to its upper end.

11. In an incandescent gas-burner having a mantle, the combination of a perforated tube rigidly secured in a vertical position on the burner and being open at both ends, and a yielding support movable on the tube to take up vibrations, said support having the mantle attached thereto. v

12. In an incandescent gas-burner having a mantle, the combination of a tube having a guide-groove formed lengthwise thereon, a wire support guided in said groove and having aspiral spring at its lower end bearing against the burner, said support having the mantle attached thereto.

13. In an incandescent gas-burner having a mantle, the combination of a tube having a guide-groove formed lengthwise thereon, a

mantle, the combination of a rigid perforated tube open at both ends and having a guidegroove arranged lengthwise thereon, a wire support for the mantle having loops surrounding said tube and offsets guided in said groove, said wire support having also a spiral spring at its lower end which surrounds said tube and bears against a portion of the burner, substantially as set forth.

15. A mantle-support comprising a rigid member supported vertically on the burner, and a yielding member having a suitable attaching end for the mantle and a spring at its lower end to take up vertical vibrations.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
